Format 02 supports Docutel ATMs. A PIN block is created
from the PIN length, a
6-digit PIN, and a user-defined numeric padding string.
If the PIN has fewer than 6 digits, it is left-justified and zero filled.
For example, for the 5-digit PIN 92389, the PIN digits are 923890.
With pad characters added, the PIN block could be, for example:
5923 8909 8765 4321
where: 98765 4321 is the padding string.
